“…For some macromolecular CPM organic components, high-voltage static electricity can destroy and ionize them, and the resulting positive and negative ions are captured by the positive and negative plates of the ESP. 59 The high voltage electric field environment also promotes the adsorption of CPM gaseous precursors by FPM. For the LLT-ESP, the lower flue gas temperature enhances the condensation of CPM gaseous precursors, which is conducive to its removal.…”

More and more attention has been paid to condensable particulate matter (CPM) since its emissions have surpassed that of filterable particulate matter (FPM) with the largescale application of ultralow-emission reform. CPM is a gaseous material in the flue stack but instantly turns into particles after leaving the stack. It is composed of inorganic and organic components. Organic components are an important part of CPM, and they are an irritant, teratogenic, and carcinogenic, which triggers photochemical smog, urban haze, and acid deposition. CPM organic components can aggravate air pollution and climate change; therefore, consideration should be given to them. Based on existing methods for removing atmospheric organic pollutants and combined with the characteristics of CPM organic components, we provide a critical overview from the aspects of (i) fundamental cognition of CPM, (ii) common methods to control CPM organic components, and (iii) catalytic oxidation of CPM organic components. As one of the most encouraging methods, catalytic oxidation is discussed in detail, especially in combination with selective catalytic reduction (SCR) technology, to meet the growing demands for multipollutant control (MPC). We believe that this review is inspiring for a fuller understanding and deeper exploration of promising approaches to control CPM organic components.

“…This aerosol composition is similar to what is commonly referred to as condensable particulate matter (CPM) in studies of coal combustion emissions in power generation. 50,70,71 CPM is comprised of inorganic and organic species that are emitted in a gaseous state and condense and form particles as the emissions cool down. 28 We note that the inorganic fraction reported in Figure 4 is likely underestimated, as there are inorganic ions that were not targeted in our IC analysis but could be present in coal emissions (e.g., Ca 70 ).…”

Torrefied biomass is a promising carbon-neutral alternative to coal. However, the effect of torrefaction on aerosol production in biomass combustion is understudied. Here, we compared the emissions and physicochemical properties of aerosols produced by the combustion of raw pine, torrefied pine, and bituminous coal. At the highest combustion temperature of 1000 °C, aerosol emission from coal was 5.2 ± 0.4 mg/MJ, while emissions from raw and torrefied pine were negligible (<10–2 mg/MJ). The coal–combustion aerosol was dominated by inorganics (85%), with a small organic fraction (15%), a composition typical of condensable particulate matter observed in power generation applications. At the lowest combustion temperature of 400 °C, aerosol emissions from raw pine (25.3 ± 4 mg/MJ) and torrefied pine (5.6 ± 0.8 mg/MJ) were dominated by organics. The organic molecules probed using electrospray ionization mass spectrometry were dominated by CHO and CHNO groups for both raw and torrefied pine. Torrefied pine emissions featured less aromatics (17% vs 22%), which can be attributed to the reduction in volatile matter content associated with torrefaction. Overall, our findings support the adoption of torrefied pine for domestic burning and power generation because of the added benefit of reducing aerosol emissions in addition to being carbon-neutral.
